APPARATUS FOR HEATING AIR WITH GAS.

SPECIFICATION forming part of Letters Patent No. 437,7 77, dated October '7, 1890. Application filed July 11,1889. Serial No. 317,239. (No model.)

To all whom it may concern:

Be it known that I, HENRY Q. HAwLnY, a citizen of the United States, residing at the city of New York, in the county and State of New York, have invented a new and useful Apparatus for Heating Air with Gas; and in illustration thereof I hereby refer to the following specification and accompanying drawings, in which- Figure 1 is a front view of the apparatus when used for the general heating of a house by warm air. Fig. 2 is a vertical section of the same. Fig. 3 is a vertical section of the apparatus when operating in part by direct radiation in the room where it is placed and in part by conducting heated air to rooms above it. Fig. et is a vertical section of the apparatus when in stove form for heating rooms by both radiation and heated air. Fig. 5 is a plan of the burner B without the slotted plate D. Fig. 6 is a plan of said slotted plate D.

Similar letters refer to similar parts in the drawings andfollowing description thereof.

As illustrated therein, the apparatus is in circular form, in which L (see Fig. 2) is the outer case, having in its bottom L theholes a for supplying the air for combustion, and the holes a for supplying air for heating, and at its top the hot-air reservoir K F is the furnace. It is placed within and consists of the case ff, theinterior casef, the burner B, placed within and near the bottom a of the case L and connected with the casef,

the heat-deflecting disk 61, and the flue-pipe P.

In the burner B, G is the gas-inlet pipe; E, the chamber for superheating the gas before using it; p, the pipes for burning it from perforations on their upper surface, (indicated in Fig. 5 by points or dots,) and D a plate over said pipes around the superheater E and forming a close partition in the interior casef'between the air-chamber beneath it and the coinbustion-chamber above it, except it has in it narrow slot-s S over and near the perforations in the pipes p.

It should be noted that the burner B, instead of being placed in and directly connected with the case ff, (as it can be, if preferred,) is placed in and connected with a separate interior case f, slightly less in diameter than the caseff, (see Fig. 2,) and open at its lower end, so that when said case f is arranged to rest upon without being fixed to the bottom L of the apparatus, as shown in Fig. 2, and the gas-inlet pipe G is disconnected from the service-pipe supplying it, both said burner and case f can be revolved upon said bottom L to permit the pipes p in the burner B to be brought in turn before the door IV of the apparatus for cleaning out the gas-jets in said pipes when required.

I is a separate heating-cylinder placed in the apparatus above its partition m and within its case L, and at a greater or less distance from them, according to the amount of air required to be heated, and it is a closed compartment, except that the pipe P enters into it and the flue R passes from it.

K are air-pipes running through the cylinder I and having their open ends connected closely with its bottom or and top '2.

IQ is a continuation of the air-chamber K, extending around said cylinder between its side and the case L and open only at its bottom and top.

K and K are air-chambers placed the former above and the latter under the cylinder I, and so connected together by the pipes K and chamber K that the air entering the chamber K at the air-inlet a in its bottom must pass upward into the receiving-chamberK V is a valve in the top of the cylinder I, arranged to act automatically.

It must be not-ed that when the apparatus is arranged as inFig. 3 the side f of the furnace F extends to and is part of its outer case above the partition-plate D and up to the airchamber K to permit of direct radiation to that extent into the room where it is used, and that when it is in stove form, as in Fig. 4, its entire outer surface is used for radiation into the room where it is placed.

The apparatus being constructed as above stated, its operation is as follows: The gas enters the chamber E and passes thence into the pipes 19 and from the perforations in their upper surface, so that it can be burned under and near the narrow slots S in the partition D, and the products of its combustion pass around the disk 61 into the cylinder I, through the pipe P, and downward in said cylinder around the air-pipes K into the outlet-flue R, placed near its bottom to give them a downward draft in their passage through said cylinder.

the chamber K through the opening a in its bottom,'pa'sses over the side and top f of the furnace F, around the partition m, (placed in the chamber K ashort distance above said furnace-top f and left open at its center for that purpose, except, as in Fig. 4, where the bottom 72 of the cylinder I takes its place,) and through the pipes K and chamber K into the chamber K from which it passes through the exitpipes K 7 'The results are combustion under conditions the most favorable possible, as the air for combustion is heated and the gas superheated before coming together, and in coming together must mix with each other under narrow slots S in the plate D, and therefore with an automatic draft-7;. 6., more or less air as more or less gas is burnedand what is more important still, and a feature in no gas-furnace known to me but my own, substantially all the heat generated is utilized in the fines of the furnace, as no air can enter them except through the said slots S and mixed with flame.

From the furnace F and heating-cylinder I being separate compartments and so arranged with reference to the air-chambers K and K and the air-pipes K that the air to be heated must pass over the side and top of said furnace and through the said pipes and chambers before it can enter the chamber K the heat generated must be much more exhaustively used than when the said furnace and cylinder form one compartment through which the products of combustion pass directly and in the hottest state, (instead of their coldest, as in my construction,) and therefore not only with great waste of heat, but without other action upon the air heated than through its outer case or side.

The valve V being placed between the cyl inder I and hot-air chamber K and arranged to act automatically, the furnace can operate safely not only with a downward draft, as shown in Fig. 2, but in case of sudden and violent pressure from careless firing of the gas when the damper in its chimney-flue is nearly closed, (more or less the case always,) as the action of said valve is entirely independent of said fine and damper.

Although I prefer the form of furnace above described (and for which a patent was issued to me by the United States November 4, 1 87 9,) for use in my apparatus on account of its superior economy-gas in competition with coal needing every advantage possibleI do not limit myself to it, as other forms can be used, provided the heat generated in them is applied as it is in my apparatus. Neither do I intend to limit myself to the flue-pipes P and R separate from each other, as they may be connected, and still the results will be good. It is also evident that the heat-deflecting disk d, although an important feature in my apparatus, is not a necessary one, and it is further evident that, when preferred, either the pipes K or the chamber K can be used alone for conducting the air to be heated from the chamber K to the chamber K and that when said pipes alone are used for that purpose the chamber K can be shut off to make it a jacketfor preventing radiation from the outer surface of the case L.

Having now fully described my invention, what I desire to claim and secure by Letters Patent is- 1. The combination, in an apparatus. for heating air with gas, of the outer case L, the gas-furnace F in the lower position thereof, the heating-cylinder I above the furnace F and separated therefrom, whereby an airchamber K is formed, an air-guiding partition m in said chamber, a flue for conveying the products from the furnace into the cylinder I, the exit-flue R from said cylinder, the air-heating pipes K passing therethrough, the valve V in the top of cylinder I, the hotair reservoir in the upper portion of the casing, and the exit-pipes therefrom, substantially as and for the purpose aboveset forth.

2. The combination, in an apparatus for heating air with gas, of the outer casing L, the gas-furnace F in the lower portion thereof, the heating-cylinder I above the furnace F and separated therefrom, whereby an airchamber K is formed, an air-guiding partition m in said chamber, a flue for conveying the products from the furnace into the cylinair-chamber, and the deflecting-disk d in said chamber, whereby the products of combustion and the air to be heated are guided close against and on opposite sides of the top of the furnace F, substantially as and for the purpose above set forth.

4. The combination, in an apparatus for heating air with gas, of the burner B, with a separate interior case f arranged to rest upon without being fixed to the bottom of said apparatus, to permit said burner and case to be revolved upon said bottom when the gas-inlet pipe G is disconnected with the service-pipe supplying it, substantially as and for the purpose above set forth.
